Mubisanzwe, coefficient de fraisse ya feri isanzwe igera kuri 0.3 kugeza 0.4, mugihe coefficient de fraux ya feri ikora cyane ni 0.4 kugeza 0.5.Hamwe na coefficient yo hejuru yo guterana hejuru, urashobora kubyara imbaraga nyinshi zo gufata feri nimbaraga nke zo gutambuka, kandi ukagera kubintu byiza byo gufata feri.Ariko niba coefficente yo guterana ari ndende cyane, izahagarara gitunguranye utiriwe usunika iyo ukandagiye kuri feri, nayo ntabwo ari nziza.
Icy'ingenzi rero ni igihe bifata kugirango ugere kubintu byiza bya coefficient de fraisation ya feri ubwayo nyuma yo gushyira feri kumwanya wambere.Kurugero, feri yerekana imikorere idahwitse biragoye kugera kubikorwa byo gufata feri na nyuma yo gukandagira kuri feri, mubisanzwe byitwa imikorere mibi ya feri yambere.Iya kabiri ni uko imikorere ya feri idaterwa nubushyuhe.Ibi kandi ni ngombwa cyane.Mubisanzwe, mubushyuhe buke na ultra-high ubushyuhe bwo guteranya coefficient bizaba bifite ubushake bwo kugabanuka.Kurugero, coefficient de friction iragabanuka iyo imodoka yo kwiruka igeze ku bushyuhe bwo hejuru cyane, bigira ingaruka mbi.Muyandi magambo, mugihe uhisemo feri yo gusiganwa, ni ngombwa kureba imikorere yubushyuhe bwinshi kandi ukabasha gukomeza imikorere ya feri ihamye kuva itangira kugeza irangiye.Ingingo ya gatatu nubushobozi bwo gukomeza gutuza mugihe habaye impinduka.
Coefficient ya feri ya feri ni ndende cyane cyangwa hasi cyane bizagira ingaruka kumikorere ya feri.Kurugero, iyo imodoka irimo gufata feri kumuvuduko mwinshi, coefficente yo guterana iba mike cyane kandi feri ntizoroshye;coefficente yo guterana ni ndende cyane kandi amapine azafatana, bigatuma imodoka umurizo kandi iranyerera.Leta yavuzwe haruguru izabangamira umutekano muke wo gutwara.Ukurikije ibipimo byigihugu, ubushyuhe bukwiye bwakazi bwo gufata feri kuri 100 ~ 350 ℃.Amashanyarazi mabi ya feri yubushyuhe mubushyuhe agera kuri 250 ℃, coefficente yayo yo kugabanuka izagabanuka cyane, mugihe feri izaba idakurikiranye neza.Ukurikije ibipimo bya SAE, abakora feri yo gufata feri bazahitamo coefficient yo murwego rwa FF, ni ukuvuga ko coeffisiyoneri yo kugereranya ya 0.35-0.45.
Muri rusange, tekinoroji ya tekinike isanzwe ya feri yashyizwe kuri 300 ° C kugeza kuri 350 ° C kugirango itangire kugabanuka;mugihe feri ikora cyane iri kuri 400 ° C kugeza 700 ° C.Byongeye kandi, ubushyuhe bwo kugabanuka kwubushyuhe bwa feri yimodoka yo kwiruka byashyizweho hejuru hashoboka kugirango habeho coefficient de fraisse nubwo ubushyuhe bwatangira.Mubisanzwe, igipimo cyubushyuhe bwa feri isanzwe ni 40% kugeza 50%;igipimo cyubushyuhe bwubushyuhe bwa feri ikora cyane ni 60% kugeza 80%, bivuze ko coeffisiyonike yo guteranya ya feri isanzwe ya feri mbere yubushyuhe bushobora gukomeza na nyuma yubushyuhe.Uruganda rukora feri rwagiye rukora ubushakashatsi niterambere ryibigize resin, ibiyirimo, nibindi bikoresho bya fibrous hagamijwe kunoza ubushyuhe bw’ubushyuhe n’igabanuka ry’ubushyuhe.
Santa Brake yashoye amafaranga menshi mubushakashatsi no guteza imbere feri ya feri mu myaka yashize, none yashyizeho uburyo bwuzuye bwo gukora igice cya metallic, ceramic, na metallic nkeya, gishobora guhuza nibikenewe bitandukanye bitandukanye. abakiriya nubutaka butandukanye.Turakwishimiye kubaza ibicuruzwa byacu cyangwa gusura uruganda rwacu.
